SHOE-DIPPING MACHINE.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed July 16, 1906- Serial No. 326,413.

To aZZ whom, it may concern.-

Be it known that 1, JOHN H. WALL, a citizen of the United States, residing at Bristol, in the county of Bristol and State of Rhode Island, have invented a new and useful Improvement in Shoe-Dipping Machines, of which the following is a specification.

This invention has reference to an improvement in machinery used in the process of manufacturing rubber shoes, and more particularly to an improvement in machines adapted to dip or varnish rubber shoes.

The object of my invention is to improve the construction of a shoe dipping or varnishing machine, whereby the operation of dipping or varnishing a plurality of rubber shoes is facilitated and the operation and construction of the machine simplified, thereby increasing the product and reducingthe cost of manufacturing the machine.

A further object of my invention is to reduce the cost of manufacturing rubber shoes, and I accomplish this object by the use of a machine adapted to varnish a plurality of rubber shoes in one operation of the machine, thereby reducing the cost of varnishing rubber shoes to a minimum.

My present invention is an improvement on the shoe-dipping machine shown in United States Letters Patent No. 817,408, issued to me April 10, 1906; and it consists in the peculiar and novel construction of a shoe-dipping machine adapted to dip or varnish a plurality of rubber shoes in one opera tion of the machine and having details of construction, as will be more fully set forthhereinafter and claimed.

Figure 1 is a vertical front view of my improved rubber-shoe dipping or varnishing machine, showing the machine in the normal position with a plurality of shoes in the machine ready to be dipped or varnished in one operation of the machine. Fig. 2 is. a top plan view of the machine in the normal position with the lasts and shoes removed from the peg-bar and the weight-levers broken away. Fig. 3 is a vertical end view of the machine, showing the operative parts in their normal position. Fig. 4 is a vertical sectional view taken on line 4 4 through the machine and showing the operative parts in the position they would assume in dipping or varnishing the shoes. Fig. 5 is an enlarged detail sectional view taken on line 5 5 of Fig. 1, showing the peg-bar and its rotating mechanism in their normal positions with the lasts and shoes removed from the pegbar; and Fig. 6 is an enlarged detail sectional view taken on line 6 6 of Fig. 5 through the peg-bar-rotating mechanism.

In the drawings, a indicates the frame of the machine; I), the varnish-tank; c, the rock-shaft; d, the lowering and elevating lever; c e, the weight-levers; f, the rotating mechanism g g, the rotating levers; h, the

peg-bar, t t, a plurality of shoe-lasts on the peg-bar, and k k a plurality of rubber shoes on the lasts.

The frame a consists of the end frames 7 7, having the upwardly-extending arms 8 8 at the rear, the bearings 9 9 on the upper ends of the arms 8 8 for the rock-shaft c, and the cross-struts 10 10, secured to the end frames, the upper cross-struts supporting the varnish-tank b, as shown in Figs. 1 and 4.

The varnish-tank b is rectangular in form. It extends the length of the frame on the upper struts 10 10 and has the beveled front and back 11 and 12, the flat bottom 13, and the ends 14 14 shaped to fit the front, back, and bottom, as shown in Figs. 3 and 4.

The lowering and elevating lever cl consists of a round bar bent at right angles and secured centrally to the rock-shaft c, with the end 15 extending over the varnish-tank in a convenient position for the operator, as shown in Fig. 3.

The weight-levers e e are secured to the rock-shaft c at each end and have the weights 16 16, adjustably secured to the levers by the setbolts 17 17, and the curved forwardly-extending arms 18 18, forming an extension of the weight-levers and adapted to support the rotating mechanism f over the varnish-tank b, as shown in Figs. 2 and 3.

i The rotating meohanismf consists of bearings 19 19 formed on the ends of the arms 18, an opening 20 in the end of each arm extending through the bearing 19, a semicircular lip 21 on the inner face of each arm formed slightly eccentric with the bearing and with the ends in an upward position, a curved lip on the inner face of each arm 18 adj aeent the semicircular lip 21, and forming a stop 22, a shaft 23 in each bearing 19 and having on its inner end a member 24 constructed to have an elongated recess 25, with the closed end 26 and the open end 27 for the end of the pegbar h, arid an arm 29, extending downward from the member in a position for the arm 29 o engage with the stop 22, with the rotating mechanism in its normal position, an arm 30,

' each end to the free ends of the arms 30 30, a

coiled spring 32, secured at one end to the end of the locking-bar 31 and at the other end to an u Wardly eXtending bracket 33 on each of the arms 18 18, the tension of the coiled springs 32 32 holding the arms 30 30 in contact with the stops 22 22 and the lockingbar 31 out of engagement with the heels of the shoes, with the mechanism in its normal position.

The rotating levers g g each have the end 34 and are placed at each end of themachine in a vertical position (when in their normal position) and are connected to a cross-bar 35, having the rearwardly-extending arms 36 36, the free ends of which are secured to the shafts 2323 of the rotating mechanism f in the openings 20 in the ends of the arms 18 1 8. The rotating levers g g, the cross-bar 35, and the arms 36 36 are all formed integral, as shown in 1 and 2. Two brackets 37 37, each having the notch 38, are secured to the top of the end frames 7 7 at each end of the tank in a position for the ends 34 34 of the rotating levers g g to enter the notches 38 38 and hold the operative mechanism in its normalposition, as shown in Fig. 3.

Thepeg-bar h has the series of pegs 39 39 eigt'ending outward from the rear face of the bar in sets of two, one set for each shoe-last *i '11. These pegs enter coinciding holes in the top of thelasts (not shown) and secure the lasts to the bar. T

T In the operation of my improved sho'e dipping or varnishing machine the tank I) is supplied ,With varnish or a similar liquid. A plurality of rubber shoes k k are placed on the lasts L t, and the lasts placed uniformly tn the peg-bar h, on which they are held by the pegs 39 39 The peg-bar h, with the lasts and shoes, is now placed in the machine with the ends of the bar in the recesses 25 in the members 24 24 of the rotating mechanism f, with the shoes in a position intermediate the peg-bar and the locking-bar 31, and with the toes of the shoes extending downward, as shown in Figs. 1 and 3. The operator now grasps the lowering and elevating lever 01 with his left hand, a rotating lever g with his hand, and by a slight upward movenient of his right hand releases the end 54 of the rotating lever from the notch 38 in the bracket 37. The lowering and elevating lever (1 is now depressed and the rotating lever 9 given a forward movement, thus operating the rotating mechanism f to partly rotate the peg-bar h, the lasts t 11, and the shoes to Sub merge the shoes in the varnish in the tank I), as shown in Fig. 4. As the rotating mechanism f starts to rotate the locking-bar 31 comes into engagement with the heels of the shoes and the arms 30 leave the stops 22 22. The locking-bar 31 is now held against the heels of the shoes by the tension of the coiled springs 32 32, thereby locking the lasts and shoes to the peg-bar in the operation of dipping the shoes. The peg-bar h is locked when in the dipping position in the recesses 25 25 by the semicircular lips 21 21 on the arms 18 18, closing over the open end 27 of the recesses 25 25, as shown inFig. 4. On the reverse movement of the levers d and g the mechanism resumes its normal position, the ends 34 34 of the levers g g are snapped into the notches 38 38 in the brackets 37 37, the locking-bar 31 leaves the heels of the shoes by the arms 30 30 coming into engagement with the stops 22 22 on the arms 18 18, and the peg-bar with the varnished shoes is removed from the machine.

Having thus described my invention, I
